[0001] This invention relates to the field of balloon launching equipment technology, specifically to a balloon ground launching equipment. Background Technology

[0002] Stratospheric balloons are primarily used in the stratosphere and are an important tool for scientific research in fields such as astronomy and upper-air meteorology. With the development of science and technology, experts in upper-air meteorology and astronomy urgently need to conduct high-altitude experiments using instrument cabins carried by stratospheric balloons. These cabins are equipped with various testing and measuring instruments to collect necessary data for scientific research.

[0003] In existing balloon ground launch equipment, the launch component's capsule changes from a horizontal to a vertical position during launch, resulting in a large capsule travel and significant impact. Other components may interfere with the launch component.

[0013] The lifting component, which is mounted on the launch direction adjustment component, is used to drive the second bladder support component to rotate and lock around the hinged end of the ridge support part as the axis;

[0014] A plurality of second capsule release components are disposed on the second capsule support component, which are used to constrain the second capsule along the length direction of the second capsule support component before launch, and to release the constraint on the second capsule sequentially along the direction from the first capsule to the load part during launch;

[0015] The load release component is disposed on the launch direction adjustment component and is used to constrain the load component below one end of the ridge support component before launch, and to release the constraint on the load component when the lift of the balloon exceeds a preset threshold.

[0016] Furthermore, when the number of second capsule release components is not less than three, one of the second capsule release components is disposed at the end of the planar support portion away from the ridge support portion, another second capsule release component is disposed at the ridge portion of the ridge support portion, and the remaining second capsule release components are disposed on the planar support portion along the length direction.

[0017] Furthermore, both the planar support portion and the ridge-shaped support portion are provided with storage grooves along the length direction, and the storage grooves are used to store the second capsule.

[0018] Furthermore, the launch direction adjustment component includes a wind direction sensing component and a direction adjustment component. The wind direction sensing component is used to sense the wind direction, and the direction adjustment component is used to synchronously adjust the orientation of the launch component, the second capsule support component, and the load release component according to the wind direction obtained by the wind direction sensing component, so that the launch direction is the same as the wind direction.

[0022] Furthermore, the wind direction sensing component is also used to sense wind speed, and the lifting component controls the lifting angle of the second bladder support component according to the wind speed and the size of the first bladder; the greater the wind speed and the size of the first bladder, the greater the lifting angle.

[0023] (III) Beneficial Effects

[0024] This invention provides a balloon ground launch device. Compared with the prior art, it has the following advantages:

[0025] 1. In terms of structural design, the second balloon of the present invention is fixed on the second balloon support component, which can be pre-lifted to a certain height under the drive of the lifting component, greatly reducing the vertical displacement difference of the second balloon before and after release, resulting in less impact on the balloon, a higher safety factor, easier control during launch, and higher reliability. In addition, the second balloon support component includes a ridge-shaped support design, and the ridge-shaped support has a certain angle with the horizontal plane. This angle, combined with the lifting angle of the lifting component, can make the angle between the last-stage launch balloon and the ground form an acute angle, so that the load part is not interfered with after the balloon leaves the control of the launch vehicle, which has self-adaptability and better reliability.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This application provides a balloon ground launch equipment that solves the problem that other components of existing launch equipment interfere with the launch components during launch.

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] Example 1:

[0039] like Figures 1-2 As shown, the present invention provides a balloon ground launch device, comprising:

[0040] A launch component 1 includes a balloon 11 and a load-bearing part 12. The load-bearing part 12 is connected to the lower end of the balloon 11. The balloon 11 is installed on the balloon ground launch equipment before launch. The upper part of the balloon 11 (i.e., the first bladder 111) is filled with gas that can generate a certain buoyancy, while the other part (i.e., the second bladder 112) is constrained by the balloon ground launch equipment and is not filled with gas.

[0041] In this embodiment, the large stratospheric balloon can hold up to 400 cubic meters of gas, has high lift, large size envelope, and large impact, and requires high reliability of the launch device. It can complete the entire launch process within 1.5 seconds and has high maneuverability.

[0042] A launch direction adjustment component 2 is used to support various components and adjust the launch direction to the downwind direction before launch;

[0043] In specific implementation, the launch direction adjustment component 2 may further include: a wind direction sensing component 21 and a direction adjustment component 22. The wind direction sensing component 21 is used to detect the real-time wind direction and wind speed, while the direction adjustment component 22 is used to realize the carrying function and adjust the orientation of the balloon ground launch equipment according to the wind direction obtained by the wind direction sensing component 21, so that the launch direction is the same as the wind direction.

[0044] In a specific implementation, the direction adjustment component 22 may include an equipment mounting platform 221 and a direction adjustment wheel 222 installed below the equipment mounting platform 221. The launch direction is adjusted by driving the direction adjustment wheel 222 to turn.

[0045] A second bladder support component 3 is used to house the second bladder 112 and to constrain the second bladder 112;

[0046] In a specific implementation, the second capsule support component 3 includes a planar support portion 31 and a ridge-shaped support portion 32. The ridge-shaped support portion 32 can be L-shaped, and one end of the ridge-shaped support portion 32 is hinged to the end of the launch direction adjustment component 32. The other end of the ridge-shaped support portion 32 is fixedly connected to one end of the planar support portion 31. To further facilitate storage, both the planar support portion 31 and the ridge-shaped support portion 32 are provided with storage grooves along the length direction for storing the second capsule 112.

[0047] A lifting component 4 is used to drive the second bladder support component 3 to rotate and lock around the hinged end of the ridge support 32 as an axis;

[0048] In specific implementation, the lifting component 4 is a hydraulic lifting cylinder or an electric lifting cylinder, one end of which is hinged to the second bladder support component 3, and the other end is hinged to the launch direction adjustment component 2. During lifting, the lifting component 4 controls the lifting angle of the second bladder support component 3 according to the wind speed and the size of the first bladder 111; the greater the wind speed and the size of the first bladder 111, the greater the lifting angle. Figure 3 As shown, the sum of the minimum lifting angle α of the lifting component 4 and the angle value β of the ridge support 32 is greater than 90 degrees.

[0049] Several second capsule release components 5 are used to constrain the second capsule 112 along the length direction of the second capsule support component 3 before launch;

[0050] In specific implementation, the second bladder release component 5 may be a locking release device as described in announcement number CN110001915B, and the number of the second bladder release components 5 shall not be less than three, with one of the second bladder release components 5 disposed at the end of the planar support portion 31 away from the ridge support portion 32, another second bladder release component 5 disposed at the ridge of the ridge support portion 32, and the remaining second bladder release components 5 disposed on the planar support portion 31 along the length direction.

[0051] A load release component 6 is used to constrain the load 12 below one hinged end of the ridge support 32 before launch, and to release the constraint on the load 12 when the lift of the balloon 11 exceeds a preset threshold.

[0052] In practice, the load release component 6 can be an automatic launch device as described in announcement number CN108516074B to achieve the above effect.

[0053] The following is a detailed description of the usage steps of the balloon ground launch equipment in this embodiment:

[0054] Step 1: Before releasing, such as Figure 1 As shown, the launch component 1 is installed onto the horizontally placed second capsule support component 3.

[0055] Specifically, the upper part of the balloon 11 (i.e., the first bladder 111) is filled with gas that can generate a certain buoyancy, while the other part (i.e., the second bladder 112) is constrained in the storage groove by three second bladder release components 5, and the load part 12 is constrained below one end of the ridge support 32 by the load part release component 6.

[0056] Step 2: After installation, adjust the overall orientation so that the launch direction (i.e., the direction from the first capsule 111 to the second capsule 112) is the same as the wind direction.

[0057] Step 3: As Figure 3 As shown, the lifting component 4 controls the lifting angle α of the second bladder support component 3 according to the wind speed and the size of the first bladder 111, thereby lifting the second bladder support component 3 to a certain angle.

[0058] Specifically, the sum of the lifting angle α of the lifting component 4 and the angle value β of the ridge support 32 is always greater than 90 degrees, which can ensure that the balloon flies obliquely upward during launch and prevent interference with the launch vehicle.

[0059] Step 4: Reference Figure 4 , 5In the order of 1 and 2, the constraints of each second bladder release component 5 on the second bladder 112 are released sequentially from balloon 11 to load part 12. At this time, the first bladder 111 and the second bladder 112 are connected, and the second bladder 112 is also filled with gas. Combined with the action of the lifting component 4, the second bladder 112 has a small vertical stroke during the launch process, resulting in less impact on the bladder and structure.

[0060] Step 5: As Figure 6 As shown, when all the second capsule release components 5 are released from their constraints, the balloon 11 generates a certain lift. When the load release component 6 detects that the lift exceeds the threshold, the load release component 6 releases the constraint on the load component 12. The launch component 1 separates from the second capsule support component 3, and the balloon 11 drives the load component 12 to rise, completing the launch.

[0061] The beneficial effects of this embodiment are:

[0062] 1. In terms of structural design, the second balloon of the present invention is fixed on the second balloon support component, which can be pre-lifted to a certain height under the drive of the lifting component, greatly reducing the vertical displacement difference of the second balloon before and after release, resulting in less impact on the balloon, a higher safety factor, easier control during launch, and higher reliability. In addition, the second balloon support component includes a ridge-shaped support design, and the ridge-shaped support has a certain angle with the horizontal plane. This angle, combined with the lifting angle of the lifting component, can make the angle between the last-stage launch balloon and the ground form an acute angle, so that the load part is not interfered with after the balloon leaves the control of the launch vehicle, which has self-adaptability and better reliability.

[0063] 2. Regarding the launch method, the number of second balloon release components can be selected as needed. In the lifting state, the second balloon release components are released sequentially. After each release, the vertical displacement of the balloon changes little, and the balloon's elevation angle always follows the wind direction. It has the advantages of good environmental adaptability, high reliability, and high degree of automation.
